带PHP / CURL的Neteller TransferOut

Question

我在使用Neteller将资金从我们的商人帐户转移到一个用户时遇到了一些问题。我成功地收到了accessToken，但是当我尝试使用transferOut时，我只得到了无效的凭据？我使用的代码是：

    $headers = array(
        "Content-type" => "application/json",
        "Authorization" => "Bearer " . $accessToken
    );

    //build the request body structure
    $requestParams = array(
        "payeeProfile" => array(
            "email" => $the_email_address_to_send_to
        ),
        "transaction" => array(
            "merchantRefId" => $transaction_id,
            "amount" => $amount,
            "currency" => $currencyCode
        )
    );

    // encode the requestParams to a string
    $requestParams = json_encode($requestParams);

    // The curl stuff
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_POST, 1);
    curl_setopt($curl, CURLOPT_URL, "https://api.neteller.com/v1/transferOut");
    curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($curl, CURLOPT_POSTFIELDS, $requestParams);
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

    // Ok lets send this lovely looking curl over
    $serverOutput = json_decode(curl_exec($curl));

显然，所有变量($transaction_id、$amount、$currency)都是适当设置的。然而，我得到的回应是：

stdClass Object
(
[error] => stdClass Object
    (
        [code] => 5279
        [message] => Authentication credentials are invalid
    )

)

我很困惑，accessToken肯定是我需要的凭证，他们已经收到了。我是否应该在transferOut的curl后置字段中包含其他内容？

提前感谢

根据user3584460's comment

$headers看起来不太好--试试$headers = array("Content-type: application/json", "Authorization: Bearer " . $accessToken);吧。至少这是根据http://php.net/manual/en/function.curl-setopt.php的格式

注意，Merchant也需要一定的长度。不知道什么-找不到参考，但8个字符不够长。
